In the fall, car accidents involving deer are more prevalent.

The Kansas Highway Patrol reported on Tuesday troopers had investigated over 40 vehicle-deer crashes during the first 20 days of October.

Last week, the Kansas Highway Patrol and Kansas Department of Transportation issued an alert to drivers.

In a media release the agencies reported 15 percent of vehicle crashes last year were deer-related, and Sedgwick County had the most, with 422 deer-vehicle crashes in 2014.

Officials say if a deer jumps in front a car, it’s best to keep driving and avoid swerving, even if it means hitting the deer. KDOT also says to avoid a collision with deer in the first place, reduce speed in or around wooded areas and be watchful at dusk and dawn when deer are more active.
